20. TSS Channels The channels collect the input sub-conditions
i.e. Helium Mass flow is a condition
Channel A (B,C) Helium mass flows are sub-conditions
Channel A (B,C) collects the 5 sub-conditions
Built in series like a chain, logic OR-gate
The design is picked up from Nuclear Industry
Channels in Relay-train & PLC-train shall have the same basic behavior
The Logic for Relay-train is based on HW
The logic for PLC-train is based on SW

28. TSS Channels to voting Channel information communicated for voting
Fiber optics are used to transfer signals long distance
The relays perform the voting logic for the Relay train
This is done by SW in the PLC-train

Created by SW in PLC-train
Connects to 2+2 actuators that performs the power break up of feeding the Ion-source and the RFQ

36. TSS Logic for Dipole magnet DM I

37. TSS Dipole magnet DM II When activated it overrides the 2oo3-voting
Activation is done in 3 independent steps
Turn off the two local switches at power supply to DM
Turn on (confirmation) the two local switches at RFQ & Ion-source cabinets
Start by turn local dial in MCR to activate
Doing it the wrong way will not override the 2oo3
When reversing the same order but dial for start TSS

40. Gateway PLC – typical use
Feedback of signals from the actuators

41. Gateway PLC- GW Gateway PLC is the TSS operational system
Handles non safety signals
Internal supervision in cabinets
Controlled signals
Interface between TSS & EPICS (MCR)
Have its own network connecting the TSS cabinets
If GW breaks down, no impact on TSS safety function

42. Gateway PLC - Functional separation
What is functional separation (Independence)?
SSMFS, Guiding document C18:
The purpose of functional separation is to achieve a design where SSC (Structure, System or Components) which are part of safety groups are sufficiently separated, for example through isolation devices, switches, valves, diodes, etc., so that the risk of common cause failures is minimised
IEC61513:
The ability to perform a required function is unaffected by the other equipment
Means to achieve independence in the design are electrical isolation
How can functional separation be solved?
Galvanically separated from Relay-train & PLC-train
Uses relay components to separate
Uses an independent network
Used for feedback of signals
Used for controlled actions in the TSS
